We propose a cloudlet network architecture to bring the computing resources from the centralized cloud to the edge. Thus, each User Equipment (UE) can communicate with its Avatar, a software clone located in a cloudlet, and can thus lower the end-to-end (E2E) delay. However, UEs are moving over time, and so the low E2E delay may not be maintained if UEs' Avatars stay in their original cloudlets. Thus,...
The focus of this paper is on a delay based backoff scheme to support m-commerce over wireless local area network (WLAN). Based on the distributed coordination function (DCF) and the enhanced DCF (EDCF) mechanisms in IEEE 802.11 and 802.lie, a novel backoff scheme is proposed. The scheme is to solve the problem of the packets loss and the decrease of performance due to the increasing contention window...
